Q. Which of the following is the most important function of Flywheel in machines such as steam engine?
Answer: helps the engine in keeping the speed uniform
Notes: A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have a significant moment of inertia and thus resist changes in rotational speed, enabling the engine to run at a constant, uniform motion. In the Industrial Revolution, James Watt contributed to the development of the flywheel in the steam engine.
